Ride 'em Cowboy - DAC

I'm specifically referring to the David Allan Coe cover, I'm not sure if it's different from the original, but this song is very special to me and I hardly know anything about it. I know there was a bucking horse way back in the 1900's named Midnight but other than that I don't know much, is it the same horse or is the song just a made up story? Would love to know, thanks
